12*6.5mm DC type magnetic buzzer, pin terminal with oscillator
circuit
Description:
Electromagnetic buzzers featuring high reliability consists mainly
of products that support automotive applications. They are directly
mountable to PCBs due to their pin terminals, and are available in
small φ12 type and φ16 type designed for broadband applications.
As a type of electronic buzzer with integrated structure, buzzers,
which are supplied by DC power, are widely used in computers,
printers, photocopiers, alarms, electronic toys, automotive
electronic devices, telephones, timers and other electronic
products for voice devices. Buzzers can be categorized as active
and passive ones.
Difference between active and passive:
An active buzzer has a built-in oscillating source, so it will make
sounds when electrified. An active buzzer can be connected just
like an LED, but as they are a little more robust, you won’t be
needing a resistor to protect them.
A passive buzzer does not have such source, so it will not tweet if
DC signals are used; instead, you need to use square waves whose
frequency is between 2K and 5K to drive it. The active buzzer is
often more expensive than the passive one because of multiple
built-in oscillating circuits.
Difference between piezo buzzer & magnetic buzzer:
| Piezo buzzer | Magnetic buzzer |

| Size | Big (10-50mm) | Small(6-25mm) |
| Resonant frequency | High(2-6KHz) | Low(1-3KHz) |
| Operating voltage | High(9-24V) | Low(1.5-12V) |
| Sound level | Louder(85-120dB) | Lower(70-95dB) |
| Current consumption | Low(5-20mA) | High(35-60mA) |
